FrankHarveyHiFi:
The 1200/1210's are designed for one purpose - to be abused by DJ's. They don't even compare to a Project Debut, as proven by an A/B demo for a customer a few years ago.
And unless you know something I don't, the 1210's are designed for the Technics arm and can't be fitted with anything else unless you're a member of the A Team. And even if this is possible, there would be no point as it's not a hi-fi product.
With respect, you should probably do some reading up before posting comments like the above. Apart from the below article which proves it's been done for a few years now, there was such an item in Hi Fi Corner in Edinburgh's Rose Street with the modified Audio Origami arm a fortnight ago. Yours for £890.

One other thing; the deck was never designed primarily for DJs only originally - it subsequently was adopted by that user group due to the deck's many strengths - the high quality motor, timing and build not least.
As for comparisons to a Debut III, I think not....maybe a close run thing which is testament to the Project, but if you compared the upgraded Technics, you have a serious midrange deck that performs and punches well above its weight. A serious contender in the sub-£1k bracket.
